Abstract
The utility model relates to a pair of improved super power clamps. One end of a clamp body is fixedly provided with a tightening mechanism, a screw rod which is driven by a swing arm is arranged in the clamp body in a penetrating way and one end of the screw rod extends in the tightening mechanism to penetrate through a piston and is combined with a movable plate. An inner sleeve pipe is arranged among the tightening mechanism, the piston and the screw rod and the middle section of the screw rod is sheathed with a movable screw block which slides on the clamp body in a screwing way. A piston which is driven by air pressure is arranged in the tightening mechanism, and a plurality of pressing rods of which the middle sections are raised are arranged between the piston and the movable plate. Inner springs which butt between the piston and the movable plate are respectively arranged among the pressing rods, and the end part of the screw rod is additionally sheathed with an outer spring which butts at the clamp body from the outer side. The piston is pressed to compress each pressing rod by the air pressure, each pressing rod butts the movable plate by the middle section of each pressing rod and the screw block can generate favorable tightening effect when the movable plate is connected with the screw rod. The utility model has the effects that the advance and retreat actions can be smoothly clamped and the utility model is not easy to wear and leak air.
Description
Technical field
The utility model is the force-doubling type clamp about improvement, is meant that especially a kind of to increase the action of clamping strength, clamping advance and retreat smooth and easy and be difficult for the force-doubling type clamp structure of wear-out failure.
Background technology
Traditional hand screw formula vice structure is with screw drive one movable block, makes it displacement and the closing clamping face in a vice body, and to produce default holding function, its major defect is:
Because the clamping power of above-mentioned manual screw vice structure is limited, there is loosening situation to take place easily, be difficult to satisfy precision machined location requirement.
Thereby be that the hydraulic type vise assembly is arranged, in the hope of the high chucking power of utilizing the oil pressure structure to be produced, overcome the easily loosening disappearance of above-mentioned traditional screw vice structure.Its major defect is:
Because the structural design of closed oil hydraulic cylinder, when causing oil hydraulic cylinder that the leakage of oil situation is arranged, can't replenish voluntarily, keep in repair, and the hydraulic type vice is slow in one's movements, can't adapt to the high efficiency running of automation processing, therefore, action is to become the direction that one of vise assembly power resources are worth the thinking development fast and have the pneumatic shuttle of suitable pressure.
As No. the 361324th, TaiWan, China patent announcement, name is called " structural improvement of force-doubling type pneumatics quick vice " (applying for No. 87214732) patent case, cooperates icon by its specification, and it mainly comprises as can be known:
One vice body;
One jiao is descended locking device admittedly is to be fixed on the screw rod by one jiao of solid nut, and assembly has in the movable jaw of dovetail face and tiger follow block in one, and fixing on the dovetail face has a semi-round ball, and it is that assembled configuration is in above-mentioned vice body;
One boosting device is made up of lid, pneumaticpiston, fixing disk body, buffering disk body and screw rod, be provided with an air pressure hand-hole that supplies the air source to enter in the lid appropriate location, and hole size can be divided into a less internal diameter A and a bigger internal diameter B in it, has internal screw thread in internal diameter A place; Pneumaticpiston is to be installed on aforementioned internal diameter A, and its central authorities have an axis hole, and is screwed together in the lid with this fixing disk body; Fixing disk body center is provided with most embedding grooves, and is provided with a screw in the center of two adjacent embedding grooves, and in abutting connection with the groove that caves in, respectively inserts one times of power bar in the embedding groove; Each disc spring of forming with a taper washer and the solid assembly of a spiral shell cushions the disk body spiral shell admittedly with one in the screw of above-mentioned fixing disk body, be placed through behind this buffering disk body with a screw rod again and be fixed on it, be fastened in respectively in the above-mentioned pneumaticpiston and lid with each O shape ring again, then be sleeved on screw rod, and be fixed on the buffering disk body with screw rod envelope body.
The structure that above-mentioned patent case is disclosed, its major defect is:
1. owing to can be out of shape by three groups of disc springs of compressing after the stressed packing between buffering disk body and fixing disk body, make buffering disk body and fixing disk body homing under the situation that does not stress in the hope of the elastic force that utilizes each disc spring, yet, disc spring is in practical application and can't produce enough deflections and elastic force, and cause elastic fatigue easily, buffering disk body and the fixing disk body is not easily separated, the situation of homing is often arranged.
2. because this lid, pneumaticpiston are to be sleeved on the screw rod periphery with O shape ring respectively to make it to produce airtight, but screw rod can make each O shape ring produce serious friction with the slip mode of helical rotation, very easily causes the damage of this O shape ring.
3. because a conduit must be reserved in vice body top side, so that being provided, the angle descends the space of locking device slippage admittedly, yet, the chip that produces, foreign matter very easily fall into this conduit in the process of working substance processing, influence screw rod and angle and descend the spiral shell between the locking device to change admittedly, cause this angle to descend the slippage of locking device to have some setbacks admittedly.
